Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Oysters, Au Gratin
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Butter a gratin dish.
Mix breadcrumbs, parsley, herbs, salt, and pepper in a bowl.
Assemble
Sprinkle the breadcrumb mixture over the butter in the dish and moisten with white wine.
Open the oysters, remove the gills, and place them in the dish, pouring the oyster juice over them.
Cover the oysters with more breadcrumbs and dot with butter.
Bake and serve
Bake for 10 minutes and serve in the dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oysters
- Provide the main flavour and tender body that the crumb topping surrounds.
- Breadcrumbs
- Form a crisp, golden topping and absorb the wine and oyster juice.
- Butter
- Adds richness and helps the crumbs brown in the oven.
- White wine
- Moistens the crumbs and adds acidity that balances the rich butter.
The step that matters
Open the oysters, remove the gills, and place them in the dish, pouring the oyster juice over them.. Keeping the oyster juice in the dish keeps the oysters moist as they heat. Overcooking makes oysters tough and shrinks them, so they need only a short bake.
Swap the parsley
How well each one fits the dish's main ingredients (oyster, butter, pepper, white wine):
- Thymefits about as well
- Parsleythe original
- Tarragonfits about as well
- Marjoramfits less well
Fit is the average pairing score against oyster, butter, pepper, white wine. Candidates are from the same food group and used in at least 100 recipes.
